Key Findings

  • 01A thermoplastic CFRP panel joined by welding was identified as the most sustainable design alternative.
  • 02Integrating LCA, LCC, and FEA from the early design stages leads to significantly more sustainable outcomes.

Application

Design takeaway

Incorporate comprehensive lifecycle assessment and cost modeling early in the design process to identify optimal material and manufacturing choices for sustainability.

How to apply

When designing complex components, use simulation tools to evaluate multiple design alternatives based on their environmental impact, cost, and performance, rather than optimizing for a single factor.

Project actions

  • 01Clearly define the scope of your lifecycle assessment (e.g., cradle-to-gate, cradle-to-grave).
  • 02Justify your choice of sustainability metrics and how they are weighted in your decision-making process.
03

Method & Evidence

AimTo develop and demonstrate a sustainability-driven design framework for aircraft components that optimizes material selection, joining methods, and subcomponent thicknesses by integrating LCA, LCC, and FEA.
MethodMathematical Modeling and Simulation
ProcedureA fuselage panel design was optimized using a framework that combined combinatorial generation of design variables (material, joining, thickness) with feasibility constraints. Sustainability was assessed using parametric LCA and LCC models, FEA for structural performance, and surrogate modeling (Random Forest). Two optimization pathways were explored: cluster-based optimization with MCDM and global optimization using Pareto front analysis and MCDM. Stability analysis of weighting and normalization techniques was performed.

Strengths & Limitations

Strengths

  • +Comprehensive integration of multiple assessment criteria (environmental, cost, structural).
  • +Application of advanced modeling and optimization techniques.
  • +Consideration of the full product lifecycle.

Limitations

The complexity of setting up and running comprehensive LCA and FEA simulations can be a significant barrier.

Reliability & validity

Reliability would be enhanced by using standardized LCA databases and consistent FEA simulation parameters. Validity is supported by the comprehensive nature of the lifecycle assessment and the use of established modeling techniques.

Think critically

How might the 'use phase' impact of a component, particularly in aerospace, disproportionately influence the overall sustainability assessment compared to manufacturing or end-of-life phases?

05

Design Principles

"Holistic lifecycle assessment is essential for optimizing complex product designs towards sustainability."

This approach moves beyond traditional eco-design by embedding sustainability considerations from the earliest design stages. By quantifying environmental and economic factors alongside structural performance, designers can make more informed decisions that lead to genuinely sustainable products throughout their entire lifecycle.

06

What This Means for Your Design

To make airplane parts better for the environment and cheaper, designers can use computer models to test different materials and ways of putting them together, looking at the whole life of the part from start to finish.

How to use in your project

  • 1.Use the integrated modeling approach as a methodology for evaluating design alternatives in your research project.
  • 2.Reference the use of LCA and LCC to justify your design choices and their environmental benefits.
